Which outcome occurs when a single fuse blows in a three-phase motor starter circuit?

💡 Explanation

When a fuse blows, single-phasing occurs because one phase is lost while energized phases try to compensate, leading to uneven current distribution and motor overheating from excessive current in remaining windings. Therefore, overheating results, rather than speed reduction, torque increase or proper function, which require balanced currents.
